In order to be processed by the brain, sound waves are converted into :
A. Electrical signal waves
In order to be carried out by our neurons, information has to be transferred as electrical wave through our brain nerves

hope this helps

Explanation :

There are many types of waves like transverse waves or longitudinal waves. The sound is a longitudinal wave and light is a transverse wave. The longitudinal waves propagate in the form of compression and rarefaction.

Compression is the position where the particles are present in bulk i.e have maximum pressure or density. On the other hand, rarefaction is the position where the particles are far apart from each other.

Due to this pressure difference, noise is created into our eardrum that moves to the brain through the auditory nerve. This noise is in the form of electrical signal waves.

So, the sound waves are converted finally into electrical signal waves in order to be processed by the brain.

Hence, the correct option is (A).

List the requirements of practical fuel?

rewona [7]

Answer:

Here we have some of the requirement of practical fuel are

1. It must contain large amount of stored energy. So that more amount of power output available to run the engines, motors etc.

2. It must occur in abundance in nature or be easy to produce.

3. The fuel must be made up of elements that combine easily with oxygen. Foe example if hydrogen molecules reacts with oxygen. Then the products are at the reaction of lower energy than the reactants, the result is the explosive release of energy and the product of water.

Two resistors, A and B, are connected in a series circuit with a battery. The resistance of A is twice that of B. Which resistor

IgorC [24]

Answer:

A dissipates more power.

Explanation:

In a series circuit, the current is the same at any point in it.
The power dissipated in any resistor follows Joule's law, as follows:

$P = I^{2} * R$

So, for a given current, the power is directly proportional to the resistance of the resistor.
In this case, as resistor A has twice the resistance of resistor B, A dissipates twice more power than B.

Help? its due in like 12 minutes lolzz

Gnom [1K]

Answer:

Question 1: the plates are moving toward one another.

Question 2: The Himalayan Mountains in India

Question 3: Because mountains are formed instead.

Explanation:

The paragraph explains that the plates continue to move closer to one another while forming multiple mountains.

The paragraph explains, " a well-known example of this is the formation of the Himalayan Mountains in India,"

The area of the Himalayan Mountains are better suited for the formation of mountains rather than volcanoes.

Have a nice day!! Good Luck!! Brainliest would be appreciated!!!

The velocity of the water in the pipe at right is given by V1 = 0.5t m/s and V2 = 1.0t m/s, where t is in seconds. Determine the

Nonamiya [84]

Answer:

A) At point 1, local acceleration = 0.5 m/s²

At point 2, local acceleration = 1.0 m/s²

B) Average Eulerian convective acceleration over the two points in the cross section shown = 0.5 m/s²

This value is positive indicating an increase in velocity and acceleration kf the fluid as the cross sectional Area of flow reduces.

Explanation:

Local acceleration at those points is the instantaneous acceleration at those points and it is given as

a = dv/dt

At point 1, v₁ = 0.5 t

a₁ =dv₁/dt = 0.5 m/s²

At point 2, v₂ = 1.0 t

a₂ = dv₂/dt = 1.0 m/s²

b) Average Eulerian convective acceleration over the two points in the cross section shown = (change of velocity between the two points)/time

Change of velocity between the two points = v₂ - v₁ = 1.0t - 0.5t = 0.5 t

Time = t

Average acceleration = 0.5t/t = 0.5 m/s²

This value is positive indicating an increase in velocity and acceleration kf the fluid as the cross sectional Area of flow reduces.
